BARREL-FINBSHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 755,374, dated March 22, 1904.

Application filed April 1, 1903. Serial No. 150,592. (No model.)

To aZZ whom, it may concern.-

Be it known that we, RoswnLL A. LANOEY and CHARLES WT. SMITH, of Townsend, county of Middlesex, and Commonwealth of Hassa chusetts, have invented certain new and useful Improvements in Barrel-Finishing Machines, of which the following is a specification.

Our invention relates to machines for fin- 1o ishing the ends of barrels, and has for one of its objects to finish both ends of a barrel at one operation.

Another object of our invention is to provide a mechanism that will finish barrels to a uniform length and diameter and leave the surface smooth.

5 Still another object of our invention is to provide means for finishing the ends of barrels of different lengths and diameters.

A further object is to provide means for automatically centering, finishing both ends of a barrel at one operation, and for releasing and ejecting the barrel from the machine when finished.

2 5, The mechanism for accomplishing these objects is set out in the drawings and description forming a part of this specification.

In the drawings, Figure 1 is a side elevation of the machine, showing all its operating 3 parts in inoperative position and a barrel in dotted lines in position upon the guides ready to be clamped and operated upon. Fig. 2 is a plan view of our improved barrel-finishing machine. Fig. 3 is a longitudinal sectional 3 5 elevation through line 3 3, Fig. 2. Fig. I is a sectional elevation on lined 4:, Fig. 2.

Fig. 7 is a sec- Fig. .8 is a sectional view of one cutter slide j and one of the adjusting devices on line 8 8, Fig. A.

, Similar letters refer tosimilar parts throughout the several views illustrating our invention.

In the drawings, A represents the bed upon Which the various parts of our mechanism are mounted. A A represent legs supporting the bed.

B B represent movable head-stocks, in 5 by means of the adjusting-bolts b 5 6 Z),

so that they may be adjusted longitudinally, as desired, by the adjusting-screws 6 .6

There are attached to the platens 6 6 the connecting-levers b b, which levers are connected at their lower ends to the reciprocat- 5 ing bars b If by means of the links b 6". Said levers d are pivoted upon rocker-shafts b b, which are mounted in hearings in the bed A. Said levers I) b have the upwardly-extending portions 1/, which are pivoted to the connect- 7 ing-links 6 which links are pivoted, by means of pins 6 to the movable beds 6. The 'two reciprocating bars 6 6 are caused to move longitudinally by means of rolls 6" b pivoted upon them, and the revolving cams Z7 5", which contact with said rolls 6 -5 The cams 6* 7) are mounted upon the revolving shaft 6 Said shaft 6 is revolved by means of the gears (Z (Z (Z (Z mounted upon their respective shafts (Z* and 05", the shaft 6Z5 being revolved through the medium of the pulley (Z The shafts CZ and (Z are mounted in suitable bearings attached to the bed A.

It will be seen by an inspection of Fig. 1 that the shaft 5 has two cams b 6* identical 5 in outline mounted upon it, each driving one of the reciprocating bars 6 I2 which, being identical in outline, construction, and operation, only one will be described. These reciprocating bars Z2 are mounted in suitable bear- 9 ings c 0, attached to the bed A of the machine.

The mechanism described, comprising the reciprocating bars 6 b and the levers b b and their respective driving mechanism and c0nnections, operate to move the head-stocks B B I toward and from each other upon the bed A of the machine to enable them to perform the operation of moving upon each end of the barrel and of clamping it firmly in an adjusted position, so that the cutter-heads may operate to finish its ends.

- are mounted upon the revolving shafts B B and carry the cutter-heads and cutters which finish the ends of a barrel. The revolving heads B have guides 41. n n n across their faces at right angles to each other, as is seen in Fig. 4, the guides consisting of dovetail grooves, in two of which is mounted the slide 0, which extends nearly across the revolving head B and has mounted at one of its ends the leveling-cutter e and at its other end the chamfering-cutter f. This slide 0 is moved longitudinally by means of the diagonal cam g roves if in the inner faces of the lugs k, in which the pins 3" bear and freely slide, as is more' the end of the barrel in order thatit clearly illustrated'in Fig. '7. Y 4

The means for operating the movable slide 0 isas follows: The said slide 0 is moved by means of a pin in the inner end of the shaft Z, operating in diagonal cam-groove j in the camblock k when said shaft Z is moved longitudinally by means of the lever Z", which may be attached to said shaft Z by any means that will permit it to revolve freely but to be immovable longitudinally in the end of said lever Z. The lever Z is attached to the rocker-shaft Z which in turn is reciprocated by means of the lever Z the link Z the lever Z, which latter is moved longitudinally by means of a roll secured to its end, which operates in the groove Z inthe slide-block Z The slide-block Z is moved vertically by means of the cam m, which contacts with the roll Z mounted on said slide-block Z. The cam m'is what might be termed a track-cami. a, it operates both to move the block Z up and to' pull it .down thereby through the connections herein set forth operating to move the cutters into cutting position to finish the ends of a barrel and to pull them back out of contact with the barrel end when the operation of finishing is complete. o e

We make no separate claim for the mechanism of the cutter-carrying head B in this application, as it forms the subject-matter of an. application filed by us October 5, 1908, Serial No. 175,729, for improvements in a mechanism for finishing the ends of barrels.

The slide 0 is moved longitudinally across the face of the revolving heads B B in the direction of the arrow shown in' Fig. 4, as shown in the illustration, although the machine may be constructed in manner to cause said slide 0 to move in either direction, as desired.

It is seen from an inspection of Fig. 4 that as the slide 0 moves to the right the chamfering-cutter f is brought in contact with the inside of the end of the barrel, thereby cutting a chamfer. At the same time the leveling-cutter e'is drawn inward to cut the ends of the staves off to an equal length. The longitudinal movement of the slide 0 is communicated to the slides 0 2 through the medium of an extension of the slide 0, extending outward from it at each side, the ends of which carry the rolls 19 19 which slide in the angu-. lar grooves 19* and 19 thereby imparting an outward movement to each of-the cutter-slides pp, causing the croZing-knife h to contact with and cut a groove in the inside of'the end of thebarrel at the same time the howeling-cutter g smooths off the inside of the end of the barrel on each side of the crozing-groove. It will be understood that the reverse movement of the reciprocating shaft Z draws the slide 0' back and through it the slides 9 and 10 back out of contact with the inside or chime of the barrel after it is finished, leaving said cutters e, f, g, and h in position where the head block B may be moved outward from maybe released from the machine. 7

The cutters eff, g, and it are adjustably secured to cutter-heads q q 11 which cutterheads are 'adjustably secured to the slides 0, p, and p bymeans of suitableadjusting-bolts having heads which fit and slide in the'T- grooves a" 770. Lugs u u a a are adjustably secured to the slides 0, p, and 10 and are provided with adjusting-screws u u and a a arranged to contact with the inner ends 'ofthe cutter-heads q, q. Q2, and'q The cutterse, f, g, and h are mounted on the cutter-heads g q, and g, respectively. 1 'VVhen it isdesired to adjust either of the cutters e, f, g', or it, the bolts fastening down, the cutterheads Q2, q, and q, respectively; are loosened and the heads adjusted in or out, as desired, by turning the adjusting-screws'u, a, a and a to the desired adjustment, whenthe securing-bolts are tightened. The adjustment just referred to is for the purpose'ofenabling the operator to finish the inside of the chime ofa barrel to the proper dimensions. I

O represents a barrel in dotted lines, and C represents gages or positioning-fingers which are mounted upon the arms C G which'arm's are in turn mounted uponthe reciprocating shaft G which is operated by the cam D, mounted upon the shaft 6 The cam D contacts with the roll'D attached to'the end of a slidable lever D which in turn is pivoted to the rocker-arm D secured to the shaft C 3 The reciprocating movement imparted to the shaft C by means of the cam D operates to eject the barrel or throw it out of the machine when finished. This mechanism, through the medium of the fingers C C, mounted on the arms G C, adjusts the barrel properly, so that when the head-stocks B B move inward the end of the barrel will be presented to the circular opening in the clamping-rings B B, which hold the barrel while the operation of finishing its ends is being performed.

E E are yielding fingers which are adapted to contact and move with the barrel when it is being forced into the retaining-rings B B and to pull it out from said ring when the.

heads B B recede from the ends of the barrel. Said fingers E E are mounted upon reciproeating rods E E, which rods are moved inward by contact with the clamping-rings B B and are locked in position by means of the locking-bolt E so that when the heads B B and the rings B B are moved outward after the barrel is finished the fingers E E will be held inwardly and against the barrel and hold it firmly from moving longitudinally in either direction and operate to pull it out fromthe clamping-rings B B. When the clamping-rings B B and heads B B have moved outward to their extreme position, the reciprocating rods E E are unlocked by the withdrawal of the locking-bolt E through the means of the lever E the end of which is moved outward by contact with the cam-surface E, mounted upon the cam'b. The said rods E E are moved away from each other by means of the spiral springs E E one end of which is attached to them, the other portion of the spring being secured upon the studs E E, mounted on the bed A.

The heads B B are revolved through the medium of belts on the pulleys B B, running on pulleys on proper counter-shafts. The mechanism for sliding the heads B B and the reciprocating shafts Z Z is driven by means of the pulley (Z having a belt running thereon from a pulley on a suitable counter-shaft.

The movement of the reciprocating shafts Z Z is again controlled by means of the clutch t on the shaft Z which enmeshes with the clutch member on the hub of the cam m, the clutch t being operated by the handle t, mounted on the bracket t The clutches s and 2. are intended to be use in case of emergency and when it is necessary for any reason to stop the longitudinal movement of the head-stocks B B or to prevent the cutters from coming into cutting contact with the barrel end. When in operation, the machine continues to make and repeat all the movements required to clamp, finish the ends of a barrel, release it from the clampingrings, and eject it without any manipulation of the operator.

The operation of our improved barrel-finishing machine is as follows: Assuming the heads B B to be moved apart, as shown in Fig. 1, a barrel is placed upon the guides C C and the clutch member sthrown into gear, when the heads B B will move inward until the ends of the barrel are firmly clamped in the rings B B. The clutch t is then thrown in and the reciprocating shafts Z Zare moved inward through the medium of the cam m, slide-block Z, the levers Z which have rolls working in the groove Z, the lever Z, the link Z, rockerarm Z rocker-shaft Z and the lever Z. The movement of the parts just described causes the reciprocating shafts Z Z to move inward, as before stated, thereby moving the slide 0 and through it the cutters e and f, which operate to chamfer and level off the ends of a barrel at the same time the howeling-cutter g and the crozing-cutter it are moved outward and perform the operation of howeling and crozing the end of the barrel,it being understood that the operation just described of finishing the end of a barrel takes place at both ends at the same time by substantially the same means. After the cutters c, f, g, and it have performed their various operations of finishing the endsof'the barrel the operating parts of the machine continue so that the cam m, through its various connections, will move the cutters out of contact with the barrel end,

and the cams Z 6 then move the heads B B outward out of contact with the barrel, the fingers E E operating to pull the ends of the barrel out of the clamping-rings B B. During the operation of pulling the ends of the barrels out of the rings by means of the fingers E E the cam Z will have revolved to a point where the contact-cam E mounted thereon will have come in contact with the end of the lever E thereby releasing the finger-bars E E, when same will be moved outward and out of contact with the ends of the barrels through the means of the springs E E ready for the insertion of another barrel. In the meanwhile the cam D will, through the medium of the roll I) which contacts therewith, move the lever D upward and through the medium of the rocker-arm D throw the arms C C upward and eject the finished barrel from the machine. The arms 0 are then returned to the position shown in Fig. 4 through the reverse of the operation just described.

It will be noted that the arms E and E are automatic in their action, being moved inward by the in ward movement of the heads B B, and serve to hold the'barrel evenly between said heads, so that its ends will enter said heads an equal distance and also serve to pull the barrel out of the heads B B when they are moved outward and hold it equidistant barrel, a bed; platens slidably mounted on said bed; head-stocks. adjustably mounted on said 7 between them, so that the barrel can be thrown out by the ejectors without the danger of its.
